Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Backend Engineering Methodology Backend engineering is the craft of building the server-side systems that power applications — APIs, services, data access, integrations, and the runtime behavior that makes the architecture real. This methodology covers implementation after target design in `software-architecture` and before quality validation in `qa-methodology`; use `software-architecture-analysis` when the current system must first be reverse-engineered. It makes runtime boundaries, transaction behavior, message handling, and coexistence seams executable without taking ownership of the surrounding architecture or migration decision. ## The Backend Engineer's Domain | You own | You don't own | |---------|--------------| | API implementation — REST/gRPC/GraphQL endpoints, request validation, response formatting, error handling, middleware chains | API contracts belong to `api-design-and-evolution`; service decomposition and target boundaries belong to `software-architecture` | | Service logic — business rules, workflow orchestration, state management, background job processing | Deployment pipeline and infrastructure — that's `platform-engineering` | …

How to install
mdr add magnus919/agent-skills/backend-engineering@sha256:d081df5433197d91The line at the top of this page pins the label git:20260821.79caa0b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
